The movie will begin shooting in late June.

Recently Gemma, 26, was linked to a role in the Jeff Buckley biopic 'Mystery White Boy'.

She is in talks to play one of the late rocker's party-loving flings while Reeve Carey - who was the lead in Broadway's 'Spider-Man' musical - has already been confirmed for the role of Jeff.

British actor Harry Treadaway and Olivia Thirlby are also in the running for roles in the film, which has been adapted by Ryan Jaffe from David Browne's book, 'Dream Brother: The Lives And Music Of Jeff And Tim Buckley'.

Jeff tragically drowned in the Mississippi River in 1997 at the age of 30. His death was ruled as accidental.
